Description

Technical Field

[0001] The utility model relates to the technical field of IVC equipment, in particular to a pipeline seal with a return air constant flow function. Background Art

[0002] The existing IVC cage sterilization equipment provides clean air to the cage in the cage by respectively setting an air supply duct and an exhaust duct at the upper and lower ends of the entire cage frame. One end of the air supply duct and the exhaust duct are connected to the main machine, and the other end is sealed by a plug.

[0003] However, the existing plugs are all in the shape of flat plates, so when the airflow flows to the plugs, the return speed of the airflow will be reduced under the blocking effect of the plugs, affecting the ventilation efficiency of the cages in the cage frame. Therefore, the pipeline seal is designed to ensure the stability of the return air in the supply and exhaust ducts. Utility Model Content

[0004] The purpose of the utility model is to provide a pipe seal with a return air constant flow function. By setting a return flow portion with an inner wall angle of 90°, the airflow in the air duct is guided by using its mutually perpendicular inner walls, so that the airflow and return flow are both located inside the pipe and distributed in upper and lower layers, thereby ensuring the stability of the return flow.

[0005] The utility model provides the following technical solution: a pipeline seal with a return air constant flow function, comprising a connecting part and a reflux part, wherein the connecting part is used to be connected to the end of the pipeline, and the reflux part is formed at the other end of the connecting part, and the inner wall of the reflux part is in a frustum shape, and the angle between the inner walls is 90°.

[0006] Furthermore, the outer surface of the reflux portion is in the shape of a truncated cone, and the end of the reflux portion is a smooth obtuse angle, which improves safety compared to the sharp angle of a cone.

[0007] Furthermore, conical grooves are evenly arranged on the outer surface of the reflux portion, and second reinforcing ribs are formed between adjacent conical grooves. The second reinforcing ribs are evenly arranged on the surface of the reflux portion, thereby enhancing the rigidity of the surface of the reflux portion and preventing the reflux portion from bending or warping.

[0008] Furthermore, a convex strip is formed on the inner wall of the connecting portion, and the convex strip is used to cooperate with the outer wall of the pipeline, thereby enhancing the connection strength between the connecting portion and the pipeline.

[0009] Furthermore, rectangular grooves are evenly formed on the surface of the connection part, and first reinforcing ribs are formed between adjacent rectangular grooves. The first reinforcing ribs enhance the strength of the connection part and reduce the bending and warping of the side walls of the connection part.

[0010] Furthermore, a boss is formed on the end surface of the connecting portion close to the pipeline side, and the boss enhances the strength of the end of the connecting portion and reduces the deformation of the connecting portion.

[0011] Compared with the prior art, the beneficial effect achieved by the utility model is: by setting a return flow portion with an inner wall angle of 90°, the airflow in the air duct is guided by using its mutually perpendicular inner walls, so that the airflow and return flow are both located inside the pipeline and distributed in upper and lower layers, thereby ensuring the stability of the return flow.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0019] See also Figures 1 to 4The utility model provides a technical solution: a pipeline seal with a return air constant flow function, comprising a connecting portion 1 and a return portion 2, wherein the connecting portion 1 is used to be connected to the end of the pipeline, and the return portion 2 is formed at the other end of the connecting portion 1, and the inner wall 23 of the return portion 2 is in a truncated cone shape, and the angle between the inner walls 23 is 90°. In the IVC cage sterilization system, air is sent into the air supply pipe by a blower, and the pipeline seal is installed on one end of the air supply pipe or the exhaust pipe. The airflow enters the air supply pipe, and the branch pipe on the air supply pipe supplies air to each cage, and the remaining airflow will flow into the pipeline seal. Under the guiding effect of the return portion 2, as Figure 4 As shown, the return gas and the supply air are both located in the supply air main pipe, and the two flow in upper and lower layers. Compared with the existing flat seal or bowl-shaped seal, the loss of air flow during the return flow process is reduced, the speed and stability of the return flow are guaranteed, and the ventilation efficiency is improved.

[0020] like Figure 1 and 2 As shown, the outer surface of the reflux portion 2 is in the shape of a truncated cone, so that the top of the reflux portion 2 is a smooth obtuse angle, thereby avoiding the formation of sharp angles on the surface of the reflux portion 2 and improving safety.

[0021] like Figure 2 As shown, conical grooves 21 are evenly opened on the outer surface of the return portion 2, and second reinforcing ribs 22 are formed between adjacent conical grooves 21. By forming evenly distributed second reinforcing ribs 22 on the surface of the return portion 2, the strength of the surface of the return portion 2 is improved, and the bending or warping of the return portion 2 is reduced.

[0022] like Figure 3 As shown, a convex strip 13 is formed on the inner wall 23 of the connecting part 1, and the convex strip 13 is used to cooperate with the outer wall of the pipeline. The convex strip 13 is embedded in the surface of the air supply pipe to enhance the connection strength between the connecting part 1 and the air supply pipe, and at the same time, the connection, installation and positioning of the connecting part 1 and the air supply pipe are facilitated.

[0023] Rectangular grooves 11 are evenly arranged on the surface of the connecting portion 1, and first reinforcing ribs 12 are formed between adjacent rectangular grooves 11, and the first reinforcing ribs 12 are distributed around the rectangular grooves 11, thereby improving the axial and radial strength of the connecting portion 1 and preventing the connecting portion 1 from bending.

[0024] A boss 14 is formed on the end surface of the connecting part 1 close to the pipeline side, and the boss 14 further enhances the strength of the lower end of the connecting part 1 to prevent deformation of the connecting side of the connecting part 1 and the air supply main pipe.
